Ultraviolet light protection by several new compounds

The Effect of Systemically and Topically Applied Drugs on Ultraviolet‐induced Erythema in the Rat

“…In these experiments the drug was applied immediately after irradiation whereas its previously reported protective effect against u.v. irradiation in man (Kahn & Curry, 1974) and the guinea-pig (McDonald-Gibson & Schneider, 1974) could be attributed to radiation absorption.…”

The Local Antinociceptive and Topical Anti‐inflammatory Effects of Propyl Gallate in Rodents

“…radiation. Kahn & Curry (1974) reported that propyl gallate was an extremely effective sunscreen. They found, however, that it was a strong contact sensitizer, in agreement with the findings of B.M.…”

Final Report on the Amended Safety Assessment of Propyl Gallate1

“…Sites were dried, exposed to an FS-40 Westinghouse sunlamp (280 to 370 nm) at a dose of three times the individual's minimal erythemal dose (MED), and evaluated at 24 h. Propyl Gallate was then reapplied to the same site, allowed to dry, rinsed with warm water for 5 min, and radiated. Sites were evaluated at 24 h. No contact sensitization, photosensitization, or primary irritation was observed (Kahn and Curry 1974).…”
